To solve this problem,
we must first examine the chemical formula of an alkene (CnH2n) and notice that
there are 2 H atoms for every 1 C atom.
<span>
Therefore this means that we can calculate the
weight percent of Hydrogen (H) using the molecular formula: </span>
<span>wt% H2 = 2n * (1.0g/mol H)/[2n*(1.0g/mol H) + n*(12.0g/mol
C)) x 100 = 14.3 wt% H
So for any alkene with mass of 0.561g, this contains
(0.143)x(0.561g) = 0.080 g H
Now, we calculate the number of moles of H this is by
dividing with the molar mass:
moles H = (0.080g H) / (1.00 g/mol H) = 0.08 moles H.
We know that there are 0.5 moles of water per mole of hydrogen,
therefore the moles of H2O formed is:
moles H2O = 0.5 * moles H = 0.5 * (0.08) = 0.04 moles H2O</span>
Answer:
<span>0.04 moles water</span>
